According to his Apostolic LetterRosarium Virginis Mariae he borrowed the motto from the Marian consecrating prayer as found in the book True Devotion to Mary by Saint Louis de Montfort. The complete text of the prayer in Latin is: "Totus tuus ego sum, et omnia mea tua sunt" ("I am all Yours, and all that I have belongs to You"). Pope John Paul II once recalled how as a young seminarian he "read and reread many times and with great spiritual profit" some writings of Saint Louis de Montfort and that:

"Then I understood that I could not exclude the Lord's Mother from my life without neglecting the will of God-Trinity"[3]
